proj/gentoo: Initial commit

This commit represents a new era for Gentoo:
Storing the gentoo-x86 tree in Git, as converted from CVS.

This commit is the start of the NEW history.
Any historical data is intended to be grafted onto this point.

Creation process:
1. Take final CVS checkout snapshot
2. Remove ALL ChangeLog* files
3. Transform all Manifests to thin
4. Remove empty Manifests
5. Convert all stale $Header$/$Id$ CVS keywords to non-expanded Git $Id$
5.1. Do not touch files with -kb/-ko keyword flags.

+GNAT, the (GN)U (A)da (T)oolchain, is a high performance Ada 95
+development environment based on the mature GCC compiler technology. It
+implements the full Ada 95 language defined by the ISO standard and is upward
+compatible with Ada 83. This is an FSF supported version, integrated with gcc.
